Common FFmpeg Use Cases

Video Conversion

Convert a video to MP4 format:

bash
ffmpeg -i input.avi -c:v libx264 -c:a aac output.mp4

What this does:

• -i input.avi: Input file
• -c:v libx264: Use H.264 video codec
• -c:a aac: Use AAC audio codec
• output.mp4: Output file

Resize Video

Change video resolution to 1280x720:

bash
ffmpeg -i input.mp4 -vf scale=1280:720 output.mp4

Extract Audio

Extract audio track from video:

bash
ffmpeg -i video.mp4 -vn -acodec copy audio.aac

Create Thumbnail

Generate a thumbnail at 5 seconds:

bash
ffmpeg -i video.mp4 -ss 00:00:05 -vframes 1 thumbnail.jpg

Compress Video

Reduce file size while maintaining quality:

bash
ffmpeg -i input.mp4 -c:v libx264 -crf 23 -preset medium output.mp4

CRF Values:

CRF	Quality	Use Case
18-20	Excellent	Professional work
23	Good	Default, balanced
28	Acceptable	Web streaming
32+	Poor	Not recommended

FFmpeg Performance Optimization

Hardware Acceleration

Enable GPU acceleration for faster processing:

NVIDIA (NVENC):

bash
ffmpeg -hwaccel cuda -i input.mp4 -c:v h264_nvenc output.mp4

Intel Quick Sync:

bash
ffmpeg -hwaccel qsv -i input.mp4 -c:v h264_qsv output.mp4

Performance Comparison:

Method	Speed	Quality	CPU Usage
Software (libx264)	1x	Excellent	100%
NVIDIA NVENC	5-10x	Very Good	10-20%
Intel QSV	3-5x	Good	15-25%
AMD VCE	4-8x	Good	15-25%

Preset Selection

Choose the right preset for your needs:

Preset	Speed	File Size	Use Case
ultrafast	Fastest	Largest	Real-time streaming
superfast	Very fast	Large	Live encoding
veryfast	Fast	Above average	Quick processing
faster	Moderate	Average	General use
fast	Moderate	Average	General use
medium	Balanced	Balanced	Default, recommended
slow	Slow	Small	High quality
slower	Very slow	Smaller	Archival
veryslow	Extremely slow	Smallest	Maximum quality

Challenges with FFmpeg

While FFmpeg is powerful, it comes with challenges:

1. Steep Learning Curve

FFmpeg has hundreds of options and parameters. The command-line syntax can be intimidating:

bash
ffmpeg -i input.mp4 -c:v libx264 -preset medium -crf 23 \
  -c:a aac -b:a 128k -vf "scale=1920:1080,fps=30" \
  -movflags +faststart output.mp4

What does this all mean? It takes time to learn.

2. Installation and Dependencies

Installing FFmpeg with all codecs can be complex:

• Compile from source for latest features
• Manage dependencies
• Handle codec licensing
• Platform-specific issues

3. No Built-in Scaling

FFmpeg processes one video at a time. For batch processing:

• Write custom scripts
• Set up job queues
• Manage server resources
• Handle failures and retries

4. Resource Intensive

Video processing requires significant:

• CPU power
• RAM (especially for high-resolution video)
• Disk I/O
• Storage space

5. Maintenance Burden

When self-hosting FFmpeg:

• Keep software updated
• Monitor server health
• Scale infrastructure
• Debug issues
• Ensure security

Modern Alternative: FFmpeg API

For developers who need FFmpeg's power without the complexity, cloud-based FFmpeg APIs offer a compelling alternative.

What is FFmpeg API?

FFmpeg API services provide video processing through simple HTTP requests. Instead of installing FFmpeg and managing servers, you make API calls.

Traditional FFmpeg:

bash
# Install FFmpeg
sudo apt-get install ffmpeg

# Process video
ffmpeg -i input.mp4 -c:v libx264 output.mp4

# Manage servers, scaling, updates...

FFmpeg API (Eranol):

javascript
// Make API request
const response = await fetch('https://eranol.com/api/v1/ffmpeg/merge', {
  method: 'POST',
  headers: {
    'x-api-key': YOUR_API_KEY,
    'Content-Type': 'application/json'
  },
  body: JSON.stringify({
    width: 1280,
    height: 720,
    images: [
      { url: 'https://example.com/video.mp4', duration: 5 }
    ],
    transition: 'fade'
  })
});

const result = await response.json();
console.log('Job ID:', result[0].job_id);

Benefits of FFmpeg API

Aspect	Self-Hosted FFmpeg	FFmpeg API
Setup Time	Hours to days	Minutes
Learning Curve	Steep	Gentle
Infrastructure	You manage	Fully managed
Scaling	Manual	Automatic
Cost	Fixed (servers)	Pay-per-use
Maintenance	Ongoing	None
Updates	Manual	Automatic

When to Use FFmpeg API

FFmpeg API is ideal for:

• ✅ Startups and MVPs - Get to market faster
• ✅ Variable workloads - Pay only for what you use
• ✅ Limited DevOps resources - No infrastructure management
• ✅ Rapid prototyping - Test ideas quickly
• ✅ Modern applications - Simple REST API integration

When to Use Traditional FFmpeg

Stick with traditional FFmpeg if you:

• ✅ Process 25,000+ videos/month - Cost-effective at scale
• ✅ Need custom codecs - Proprietary or experimental features
• ✅ Have strict data sovereignty - Cannot use cloud services
• ✅ Already have infrastructure - Existing servers and expertise
• ✅ Require offline processing - No internet dependency

FFmpeg Best Practices

1. Always Test First

Test commands on small files before processing large batches:

bash
# Test on first 10 seconds
ffmpeg -i input.mp4 -t 10 -c:v libx264 test_output.mp4

2. Use Two-Pass Encoding for Best Quality

For optimal quality at target bitrate:

bash
# Pass 1
ffmpeg -i input.mp4 -c:v libx264 -b:v 2M -pass 1 -f null /dev/null

# Pass 2
ffmpeg -i input.mp4 -c:v libx264 -b:v 2M -pass 2 output.mp4

3. Preserve Metadata

Keep original metadata when converting:

bash
ffmpeg -i input.mp4 -c copy -map_metadata 0 output.mp4

4. Enable Fast Start for Web

Optimize MP4 files for web streaming:

bash
ffmpeg -i input.mp4 -c copy -movflags +faststart output.mp4

5. Monitor Progress

Show progress during encoding:

bash
ffmpeg -i input.mp4 -c:v libx264 -progress pipe:1 output.mp4

FFmpeg vs Other Tools

Tool	Best For	Pros	Cons
FFmpeg	Everything	Powerful, free, flexible	Complex, CLI-only
Handbrake	Desktop conversion	User-friendly GUI	Limited automation
Adobe Media Encoder	Professional work	Industry standard	Expensive, heavy
VLC	Quick conversions	Simple, familiar	Limited options
FFmpeg API (Eranol)	Developers	Easy integration, scalable	Requires internet

    'Content-Type': 'application/json'
  },
  body: JSON.stringify({
    width: 1280,
    height: 720,
    images: [
      { url: 'https://picsum.photos/1920/1080.jpg?random=1', duration: 3 },
      { url: 'https://picsum.photos/1920/1080.jpg?random=2', duration: 3 }
    ],
    audio_url: 'https://example.com/audio.mp3',
    audio_mode: 'video_length',
    transition: 'fade'
  })
});

const job = await response.json();
console.log('Processing:', job[0].status_url);

Conclusion

FFmpeg remains the most powerful and versatile video processing tool available. Its open-source nature, comprehensive format support, and active development make it indispensable for media workflows.

However, the complexity and infrastructure requirements can be overwhelming. For modern applications, FFmpeg APIs provide the same power with dramatically simplified integration.
